KINGSTON (AFP) Jamaica's treble Olympic sprint champion Usain Bolt believes his world record-setting triumph in the 200m in Beijing must have stung previous world record-holder Michael Johnson more than the American admitted.

"I know he was lying," Bolt said of Johnson's claim that he didn't feel a pang of loss when Bolt sliced two-hundredths of a second off his 12-year-old mark with a sizzling victory in 19.30sec.

"I am sure Johnson thought his 19.32 would have been there for a longer time," added Bolt, who also won the Olympic 100m in a world record of 9.69sec and was part of Jamaica's triumphant, world record-setting 4x100 relay in Beijing.

Bolt, 22, said earlier this month he will bypass next year's early Golden League meets to better prepare for the 2009 world athletics championships in Berlin.

But he says he hasn't got another 100m-200m double in mind as specific goal at the worlds.

"I have not yet set myself any goal, but to stay on top," he said.

To do that, the Jamaican hinted, he might have to run even faster.

"Everyone will be gunning for me, but that will only push me to do better," he said.
